On May 31, 2017, Ontario Attorney-General Yasir Naqvi introduced Bill 142, entitled “Construction Lien Amendment Act, 2017”. The Bill follows upon a report commissioned by the Ontario government and prepared by Bruce Reynolds and Sharon Vogel entitled “Striking the Balance: Expert Review of Ontario’s Construction Lien Act”. If enacted, the proposed legislation will introduce what is arguably the most sweeping set of changes that the Canadian construction industry has ever seen.
